I am also surprise that there isn't 4K. I dont normally watch VOD so not sure if there are any movies 4k on there. No big deal really since this box is IPTV only. Im sure there are other means of getting 4k. This box does have a really good quality picture then other boxes that i have tested.
sounds like this box is compatible with ALL KINDS OF STALKER SERVERS AND ALSO EMULATORS. if it is then definitely one of the best box for iptv only if I'm not wrong.
